CVE-2020-8115 Information

Description

A reflected XSS vulnerability has been discovered in the publicly accessible afr.php delivery script of Revive Adserver = 5.0.3 by Jacopo Tediosi. There are currently no known exploits: the session identifier cannot be accessed as it is stored in an http-only cookie as of v3.2.2. On older versions however under specific circumstances it could be possible to steal the session identifier and gain access to the admin interface. The query string sent to the www/delivery/afr.php script was printed back without proper escaping in a JavaScript context allowing an attacker to execute arbitrary JS code on the browser of the victim.
